Definitions

  • the present invention relates to tyre recycling, and specifically to a device and method for removing rubber from vehicle tyres.
  • Rubber tyres such as those used on most motor vehicles, require replacement as they become worn and lose their tread.
  • Replacing a tyre typically involves taking the vehicle to an appropriate garage. At the garage the wheel and tyre assembly is removed from the vehicle, the tyre is removed from the wheel rim, a new tyre is fitted to the wheel rim, the wheel and new tyre assembly is balanced and then refitted to the vehicle.
  • a device for removing rubber material from a vehicle tyre comprising: means for supporting a tyre, cutting means for removing rubber material from the tyre; actuating means for moving the cutting means and the wheel and tyre assembly relative to one another; processing means for automating the movement of the cutting means and the wheel and tyre assembly relative to one another; and sensor means for determining the depth of rubber material present on the tyre,
  • any suitable sensor means known in the art may be used, for example ultrasound, x-rays, lasers or vibration detectors.
  • the depth of rubber material on the tyre could also be measured, for example, by using a sharp or heated implement to bore a hole into the tyre until the carcass is reached, and then measuring the depth of this hole.
  • a device for removing rubber material from a vehicle tyre comprising: means for supporting a tyre, cutting means for removing rubber material from the tyre; rotation means for rotating a wheel and tyre assembly supported on the device relative to the cutting means; the rotation means comprises a rotatable support, having an expandable chuck for location through a substantially central aperture in the tyre for securing a tyre thereon, and wherein the device further comprises means for rotating said support such that the cutting means can contact the tyre and remove rubber material therefrom.
  • the chuck can be adjusted to secure wheels having apertures with different diameters, and may be expandable so that it may support a wheel and tyre assembly or it may be expanded to fit the tyre alone. This will mean that the garage will be able to shred tyres which have already been removed from the wheel and well as tyres prior to fitting replacement tyres to the wheel.
  • the term 'vehicle' used herein is intended to include, inter alia, cars, lorries, motorbikes, caravans, and trailers.
  • the machine is, however, suitable for use with all tyres of pneumatic tyres.
  • the rotatable support is connected to a shaft which is caused to rotate by any suitable means for example a motor located in the main housing of the device.
  • the shaft and rotatable support may be orientated substantially vertically, substantially horizontally or at any angle there between.
  • the angle of inclination of the rotatable support may also be adjustable according to the operator's preference.
  • the shaft is orientated such that it extends substantially horizontally, so that the wheel and tyre assembly is rotated in a substantially vertical plane.
  • the main housing may be provided with wheels on its base to enable the device to be easily moved around a garage or tyre-bay.
  • the wheels are lockable so that the device cannot move around during use.
  • the device 10 is intended for use in a garage, or tyre change bay.
  • a vehicle enters the garage or tyre change bay and a wheel and tyre assembly 12 is removed from the vehicle in the normal way.
  • the wheel and tyre assembly 18 is placed on the rotatable support 16 of the device 10 such that the three jaw chuck 20 extends through an aperture 15 (Figure 1) in the centre of the wheel 14.
  • the three jaw chuck 20 is radially expanded within the aperture 15 until the wheel and tyre assembly 1.2 is firmly secured on the device 10.
  • the cutting blade 22 is angled relative to the tyre 13 so that the rubber material 24 which is removed from the tyre 13 is directed towards, and collected in, waste catcher 36. Once all of the rubber, or the majority of the rubber, has been removed from the tyre, the tyre carcass is then removed from the wheel rim 14 and the wheel rim 14 is removed from the device 10.
  • the cutting means or another tool could be used to further process the carcass, for example, by shredding or splitting the carcass or removal from the wheel rim.

Abstract

L'invention porte sur un dispositif (10) et sur un procédé pour retirer le matériau de caoutchouc (24) des pneus de véhicule (13). Le dispositif comprend un couteau (22) pour retirer le matériau de caoutchouc (24) du pneu (13). Un ensemble de roue et de pneu (12) est retiré d'un véhicule et supporté sur le dispositif (10). Le couteau (22) peut être positionné en contact avec le pneu (13) et le dispositif (10) peut déplacer le couteau (22) et l'ensemble de roue et de pneu (12) l'un par rapport à l'autre, de telle sorte que le matériau de caoutchouc (24) est retiré du pneu (13). Des moyens de détection sont utilisés pour déterminer la profondeur du matériau de caoutchouc présent sur le pneu et il est prévu un mandrin extensible (20) pour positionner la roue.
